Adrenaline MMA IV takes place at Mid American Center in Council Bluffs, Iowa. The main card airs live on HDNet.

Sylvia looks to break out of a slump that has seen “The Maine-iac” earn just one win in his past five trips to the cage. Sylvia most recently fought in June when the former UFC champion was stopped in just nine seconds by former boxing champ Ray Mercer.

Meanwhile, Riley looks for the biggest win of his young career. After turning pro in 2007, Riley has earned five of his six career wins by stoppage, a run that includes four wins in the first round.

Co-main event fighter Alexander also looks to break a recent slide. Granted permission by the UFC to fight outside of the organization, Alexander has suffered three-straight defeats.

Facing Alexander is Pendergardt, who after a respectable 8-3 start to his career has gone just 3-11 in his past 14 contests.

Outside of the co-main events, Reiner and Petz meet in a contest of two fighters who struggled a bit on the national stage.

Reiner appeared in the UFC twice in 2007, though he dropped both contests. Reiner suffered a unanimous-decision loss to Josh Burkman before falling victim to an Anthony-Johnson-highlight-reel finish in just 13 seconds.

Petz garnered a longer stay in the UFC, compiling a 2-3 record in five trips to the octagon in 2006 and 2007. Petz’s run includes decision wins over Luigi Fioravanti and Sam Morgan.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
